Download file without download button

Using Streamlit
1

Hi,
is there a way to download a file without using the download button? I have a button, that, if clicked, runs some different commands and one of them is downloading a file. So I’m using a st.button, I can’t use a st.download_button because I must perform different tasks at once.

How can I do that?

def download_base64_file(b64, download_filename):
    id_link = '_'+str(uuid.uuid4())
    components.html(
        f"""<html><body>                                   
        <a href="data:application/pdf;base64,{b64}" download="{download_filename}" id="{id_link}"></a>""" +
        """<script>                                    
                window.onload = function () {                                            
                    document.getElementById('""" + id_link + """').click();
                                    };                                        
                                </script>
                            </body></html>                                    
                            """, height=0, width=0)
